Animenewsnetwork - In the middle of this episode, Kaori and Kosei sit in the music room and discuss the piano competition she's entered Kosei into. Then Kosei says something that's very revealing. He says that in that room, it feels like he's in a "world with just them", but when he leaves, that world will go away. Kaori is the "girl his friend likes", and of course Kosei is in the middle of his own love triangle, though he's oblivious to it. This episode is all about those outside relationships, along with Kosei and Kaori's growing bond.
